Title: Method of monitoring cyclically moving body
Inventor: TAKEYASU KAZUHIRO
IPC: G01M99/00
Filed: 1981-01-30
Abstract: PURPOSE:To detect anomalies of a cyclically moving body with high accuracy and  high reliability by a method wherein correlation functions in the given number are computed from time sequential data so as to obtain the mean and variance of prediction  errors. CONSTITUTION:An electric signal from a vibration detecting transducer 1 is stored in a  memory unit 3 via a sampling circuit 2. A correlation function arithmetic unit 4 takes  in the latest sampling values in the number N for each period of a given time, which  values have been stored in the memory unit 3. A memory unit 7 stores therein the  degre M for a system such that prediction errors become minimum based on time  sequential data in the normal state, and correlation functions Ri in the normal state.  The correlation function arithmetic unit 4 computes the correlation functions Ri in the number M+1 from the time sequential data and then outputs the result together with  the latest time sequential data in the number M to a mean and variance arithmetic  unit 5. A memory unit 8 stores therein the mean and variance of prediction errors and  the mean of a service time, and these data are input to the mean and variance arithmetic unit 5. The mean and variance arithmetic unit 5 computes the mean and variance of prediction errors so as to predict occurrence of anomalies and the service life.
